How We Source Our Medication Data

Data Sources

• FDA drug labels (openFDA drug/label): uses, warnings, boxed warnings, side effects, interactions, and contraindications on each medication guide are quoted from current FDA prescribing labels, with the label's SPL set ID and effective date shown on the page.
• FDA Adverse Event Reporting System (FAERS, openFDA drug/event): the "most-reported adverse events" counts. These are voluntary, unverified reports — they do not establish that a medication caused a reaction.
• FDA recall & enforcement records (openFDA drug/enforcement): the medication safety monitor.

How the Interaction Checker Works

Our interaction checker (81 combinations) is built by automatically scanning the FDA prescribing label of each medication in our library for mentions of the other medications we cover, then classifying severity from the label section and wording (contraindications → contraindicated; strong caution wording → major; monitoring language → moderate). Every interaction page shows the exact label sentence it came from.

Limits: this is automated text analysis of FDA labels, not a comprehensive clinical interaction database like those your pharmacist uses. It only covers medications in our library, and it can miss interactions. It must never replace review by your prescriber or pharmacist.

Freshness

Data refreshes automatically from openFDA on a daily schedule. FDA label data last synced 2026-09-01. Each medication guide shows its own label effective date and sync date.

What Bridgeway Adds

Bridgeway clinicians may add clinical perspective and family guidance on individual medication guides; those sections are clearly attributed. Everything else is FDA-sourced. Medication decisions are always made with your provider — our library is for education, not prescribing.
